GATE.

SPECIFICATION forming part of Letters Patent Nc. 340,861, dated April27, 1886.

Application filed December 31, 1885. Serial No. l8',lt29. (No model.)

.To @ZZ whom it' may concern:

Beit known that I, COMMODORE B. CLARK, a citizen of the United States ofAmerica, residing vat-Villiams, in the county of Colusa and State ofCalifornia, have invented certain new and useful Improvements in Gates;and I do hereby declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference beinghadto the accompanying drawings, and to letters orfigures of referencemarked thereon, which form a part of this specification.

My invention relates to certain new au d useful improvements invertically-swingi ng gates; and it consists in the construction andcombination of the parts, as will be hereinafter fully set forth, andspecilically pointed out in the claim. In the accompanyingdrawings,which illustrate my invention, Figurel is aperspective view.Fig. 2 is a side view showing` the gate in a position to close orobstruct the gateway in full lines and depressed in dotted lines.

A represents a frame-work which is sunk beneath the bed of the road, andis provided with a transverse slot, a, between which the bars b and bare pivoted. The lower portion of the transverse slot a is trough-shapedand is inclined so that any water that may collect therein will flow outof the opening a.

The frame A is provided at one end with vertical posts B I3, which areconnected to each other by a cap-piece, B', so as to leave a verticalopening, c, between the same, and near the opposite end of the frame Aare secured two parallel posts, C C, said posts having attached at theirupper ends a cross-beam, D, the ends of which are provided with pulleysd d. The uprights or posts C C have secured between the same at a slightdistance above the top of the gate a block, E, the end of which isbifurcatcd, and between said bifurcated portion is pivotally secured alever, F, which lever' extends upwardly so that its end will playbetween the outwardly-exteudin g bars G, which are attached near theupper ends ofthe uprights C C. Between the outer endsof the bars G ispivoted a roller, g, over which pass cords, which also pass over pulleysg', which are attached above the crossbeam D, said cords passing fromthence over the pulleys d. Guide-pulleys h are supported in asuitableframe under the beam D, and around these pulleys pass cordswhich are attached to the upper end of the lever F, said cords extendingoutwardly from said pulleys to the pulleys d. Thus it will be seen thatby drawing upon the cords c the lever will be drawn toward the pulley g,and when the cords c are pulled upon the lever will be moved in anopposite direction. The bars Z) b' of the gate are each at their lowerends pivoted to the side walls of the slot a, and the bar Za at the endofthe gate has a member, b, which projects at right angles thereto, andsaid mem ber carries at its outer end an adjustable counterbalancingweight, I. The rails f f of the gate are pivotally attached to the barsb b', and the upper rail is provided with a loop or hand-piece, fC

lVhen it is desiredto pass through the gate or depress the same withinthe slot,the cord e is drawn downwardly, which will move the lower endof the lever inwardly toward the lower end of the uprights C C, whichcarries with it thc member b of the bar b', the lower end of the leverbeing connected thereto by a chain, t, and after passing over the gateto close the same the cord c is drawn upon, which moves the lever F inan opposite direction, so as to raise the gate, said lever beingconnected to the member b by the chain i. Then the gate is closed,themember b will rest upon the block II, and when the gate is open or depressed below the surface of the road-bed the end ofthe bifurcated blockwill serve as astop, so as to prevent the bar b tilting beyond itscenter.

The pulleys around which the operatingcords e c pass are protected fromthe weather by suitable casings or housings. I

Iam aware of the patent of La Baw,.No. 156,888, granted November 17,1874, and also of the patent of Crandall,No.111,322, granted January 31,1871, and I do not claim,broadly, any feature set forth in either ofsaid patented constructions.

I claim-- In a folding gate, a casing located beneath the road-bed andprovided with a slot in which are pivotally secured the ends of the barsZ) b', the bar b/ having' a member projecting at right ICO anglestherewith, and provided with a weight, In testimony whereof I affix mysignature in 1o the uprights C @,suppoitingzt bar, 1),@ frame, presenceof two Witnesses. G, and block E, in combination With the puileys d d gg h, and cords e e', which pass COMMODORE B.
